- To all whom it may concern:

- Be it known that l, Inn S. MoNAUen'r, a

' citizen of the United States, residing at Chicago, in the county ofCookand State of Illinois, have inventedcertain new and use- 'fulImprovements in Adjustable Tracks for and the invention consists in themeans supporting the track for adjusting the vertical position of thedoor.

When atrack for a sliding door is secured to its support, and a doorsuspended therefrom, one end of the track lies concealed behind thepartitions between which the door is adapted to slide. For variousreasons,

Specification of Letters Patent. Application filed-June 5, 19m. seennast est.-

such "as the warping of a beam to which the track may be secured or thesettling of the floor, or'tlie partitions on either side of the tracklosing their alinement if the track is secured to the same, the doorloses its pro er vertical position relative to the floor so tiat it doesnot slide'frcly.

(lnc oi the objects, therefore, of the invention is to provide means forreadily adjusting the track so as to bring the door into its propervertical position without removing the track from its support,orvremoving any of the adjacent parts relativc'thereto.

.In the accompanying drawing, Figure 1 is a side elevation of myadjustable track, hav-' ing a door slidably connected thereto, with thepartitions inclosing the track broken away;Fig. 2 is an end elevation ofthe upper portion of Fig, 1 at the left end thereof; Fig. 3 IS a viewsimilar to Fig. 1 showing a modlhed form of my 1nvcnt1on;-and Fig. e isi a cross section on line 4M4 of Fig.{

Referring now more specifically to the drawings, 5 represents a track oftubular form, having a longitud' ial slot at the bottom thereof andadapted to cooperate with a hanger secured to a door, that will behereinafter described. Asa means for support ing the track a series ofbrackets 7 are used which partially encirclethe track and are l to havea sliding engagement therewith so that they may he moved to any-suitable position on the track. Each bracket isprovlded with a hanger arm 8,that is prof erably l 'ormed integral-with the bracket por- Patented ma1 1, 1909.

tion 7,-whichar1 n 8 is providedon one of its edges with'ra'tchet teeth9;

10 re resents a su means of the SCIGWSlZ, said keepers 13 on f theouteriiices thereof port for the track, and to Whio are secure a seriesof lates 11 -by 1 ates hav ng preferably formed integral therewith and.

through which thehangerarm's 8 are ada'pted to pass.

Pivotally mounted within the keepers 13' I are clamps herein shown as inthe nature of pawls 14 having ratchet teeth 14 on one edge adapted toengage the ratchet teeth 9 on'the hanger-arms, said en agement betweenthe teeth-being effected by a movement of the pawl 14 in one direction,and a disengagement therefrom by a movement in the opposite 'direction,said pawls bein pivoted by means of the pins l5 passe through the plates11 and keepers 13. Each pawl is provided with an arm 16, and pivotallyattached to each arm 16 is a connectingv rod 16*, one end of which.terminates at the opening of the doorway andhas a lever arm 1 7 pivotedthereto bymeans of the pivot pin 18. A pivot bolt 19 secures theleverarm 1'? to the sup ort,10, which lever arm extends-down be ow thesupport 10 so that the same In ay be readily grasped. As a means forsecuring thelever arm in any set osition a segment 20 18 provided havinga slot 21 therein and a sliding bolt "22 is connected to the lever armand extends through the slot 21 of the segment 20, having a wing nut'23therei on so that'by amovement of the wing nut the lever arm may b drawnagainst the seg-- ment 20 or release; therefrom.- the device is shownwith ratchet teeth in en+ In Kg. 1

gagement and the, track in locked position, whereas in Fig. 3 the leverarm has been moved to thev lei-tthere y moving the arms of the pawls tothe right, and consequently thrmving the ratchet teeth out of engagementwheroup fn the track may be alined. When the tradlr is in its properposition to aflord the'right vertical adjustment ofthe loo door, thelever is thrown to the right, as

viewed in Fig. 1, and the'parts are firmly locked.

It is sonictin'ics (liflicult,- especiallv where hoavyi'doors are used,to adjust the tiack'in its proper position as the door has to besupported While so doing, and therefore in Figs.

3 and 4 I have shown a modified form of involition wherein there is disosed substantially centrally of the trackv a racket'24 havingahorizontal lug 25 formed integral there- "with, which lug is aperturedto receive a vow having wheels 32 journaled thereon and 'space betweenthe two partitions constitutor contact might serve equally as well asthe bolt 26 that has a threaded engagement with a support 27 secured tothe su port 10 by means of the screws. 28. In t 1s construction to raiseor lower the. track to its proper'position the screw 26 ma be eithermoved up or down thereby adjusting the door relative to the floor andaffording an intermediate su port readily accessible so as to ermit eiterend of the track to 'be rocke to secure the properalinement of thetrack parallel with the floor.

. In the drawings 29 represents the partition concealing the backportion of the track; 30 is'a door to which are secured hangers 31Within the tubular track, while 33 is a'partition at the outer end ofthe track, the

ing the doorway, and 40 represents the floor. It is to be understood,however, that more than two supports may be used, and where the trackrequires more than two of said sup ports the arms of any additionalpawls may e connected to therod 16, the same, as the arms 16 areconnected. Nor is the inven tion limited to the use of teeth on theedges of they hanger arms and pawls since-the latter have a clampingaction as well as a positiv'e holding action, and a frictional surfaceratchet teetri, and therefore without confining myself to the specificconstruction shown,

claim: 7

'1. In a door hanger the combination of a support, a clamp memberpivotally secured track, and means for moving said clani'pl support,substansupport', pawls-provided with teeth pivoted to said support, atrack, brackets secured to said tracli, said brackets provided withteeth, 7

and means for moving said pawls whereby the teeth on said pawls andbrackets cooperate to hold said track in locked stantially as described.M

04. In a doorhanger the combination of a position, subsupport,pawlsprovided with teeth pivoted to said support, a track, bracketssecured to said track and rovided with teeth adapted to cooperate withthe teeth on said pawls,

and means for simultaneously movingsaid pawls to secure said track inthe proper verti gal position relative to said support, substantially asdescribeds f 5. In adoor hanger the combination of a support, pawlspivotally secured to said supv port provided with teeth,& track,brackets secured to said traek'and provided with cooperating teeth, a'rodsecured to-said pawls, for simultaneously moving said teeth intoengagement or disen agement for the purpose of adjusting saitrackrelative to said support,- and means for operating said rod andholding the same in adjusted position.
